SMOKE-BELL.

Specification of Letters Patent.

Patented Aug. 18, 1908.

Application filed April 20, 1908. Serial No. 428,063.

To all whom it may concern:

Be it known that I, GEORGE ALPHA MIL- HOLLAND, a citizen of the UnitedStates of America, residing at Pittsburg, in the county of Allegheny andState of Pennsylvania, have invented certain'new and useful Improvementsin Smoke-Bells, of which the following is a specification, referencebeing had therein to the accompanying drawing.

This invention relates to a smoke bell and the primary object of myinvention is to provide a novel bell for causing a diflusion of the heatunits emitted by a gas light.

A further object of my invention is to provide a simple durable andinexpensive smoke bell that can be easily suspended over a light orlamp, either to cause a diffusion of the heated air above the light orlamp, or to protect a ceiling from the lamp or light.

WVith the above and other objects in view which will readily appear asthe invention is better understood, the same consists in the novelconstruction, combination and arrangement of parts to be presentlydescribed and then specifically pointed out in the appended claims.

In the drawings, Figure 1 is an elevation of my smoke bell suspendedabove the light or lamp of a chandelier. Fig. 2 is a cross sectionalview of a smoke bell partly in elevation. Fig. 3 is a horizontalsectional View of a smoke bell partly broken away.

In the accompanying drawings, 1 designates a metallic plate or disk towhich is secured by rivets 2 a hook 3, constituting a hanger whereby thebell can be suspended from a suitable support above a light or lamp 4.The-rivets 2 also serve to hold a U shaped arm 5, in engagement with the5 plate, said arm being provided with two diametrically opposed screws 6and 7, the screw 6 extending through the plate or disk land having asuitable bearing 8 for the shaft 9 of a bladed wheel 10, the oppositeend of said shaft resting in the end of the screw 7, which extendsthrough the arm 5. The screws 6 and 7 upon the confronting sides of thearm 5 are provided with jam nuts 11 having levers 12, whereby after thescrews are adjusted they can be locked in a fixed position. The bladedwheel 1() is provided with a central spider or reinforcement 13 suitablysecured to the shaft 9. The blades of the wheel 10 are formed at such anangle that the heat emitted by the light or lamp 4 will be scatteredabout the compartment in which the light or lamp is located.

The bearings in the ends of the screws 6 and 7 can be jewel or any typeof bearing that will reduce the friction of a shaft to a minimum.

The smoke bell in its entirety is constructed of light and durablematerial that can be finished to harmonize with the gas or lamp fixturein connection with which it is used.

Having now described my invention what I claim as new, is

1. A smoke bell comprising a plate or disk, a hook, a U-shaped arm,rivets securing said hook and said arm to said disk or late, screwscarried by the confronting sic es of said arm, a shaft revolubly mountedbetween said screws, a bladed wheel, a spider or reinforcement carriedby said Wheel and fixed upon said shaft, and am nuts mounted upon saidscrews.

2. A smoke bell comprising a plate or disk, a hook, a U-shaped arm,screws adjustably mounted in said arm, a shaft revolubly mounted betweensaid screws, a bladed wheel fixed upon said shaft, jam nuts carried bysaid screws, and means for securing said arm and said hook to said plateor disk.

3. A smoke bell comprising a plate or disk, a hook attached thereto, anarm attached thereto, screws carried by said arm, a shaft j ournaledbetween said screws, a bladed wheel fixed upon said shaft, and means forfixing said screws in said arm.

4. A smoke bell comprising a plate or disk, a hanger secured thereto, aU-shaped arm carried by said plate, oppositely disposed screws mountedin said arm, a shaft revolubly mounted between said screws, and a bladedwheel carried by said shaft.

5. A smoke bell comprising a plate or disk, a hanger secured thereto, aU-shaped arm carried by said plate, oppositely dis osed bearings carriedby said arm, and a b aded wheel revolubly mounted between said bear-HIUS.

ln testimony whereof I affix my signature in the presence of twowitnesses.

GEORGE ALPHA MILHOLBAND.
